Abstract
The invention discloses a kind of pyrimethanil-contain bactericide and the bactericidal composition and its preparation of Nikemycin, it is related to technical field of pesticide.The bactericidal composition contains active component pyrimethanil and Nikemycin, and the mass ratio of pyrimethanil and Nikemycin is 1:40~10:1.Composition of the invention there is obvious synergistic effect relative to single dose, Cereal, each planting fruit-trees, vegetable crop disease can effectively be prevented and treated, such as wheat powdery mildew, rice blast, Glomerella cingulata, leaf muld of tomato, powdery mildew of strawberry, gray mold of cucumber, reduce the dosage of agricultural chemicals, save drug cost, the not enough and insect of single dose is made up simultaneously to its tolerance, improves insecticidal activity.
Description
Technical field
The present invention relates to technical field of pesticide, more particularly, to the bactericidal composition of two kinds of insecticidal active compound mixtures,
It is specifically related to the bactericidal composition and its preparation of a kind of pyrimethanil-contain bactericide and Nikemycin.
Background technology
In pesticide research, the composition of different cultivars is compounded, is prevent and treat resistant insect or bacterium very common
Method.Heterogeneity is compounded, according to the effect of practical application, to judge that certain compounding is synergy plus and or antagonism.It is multiple
It is formulated well with synergy, due to significantly improving actual prevention effect, reduces the usage amount of agricultural chemicals, so as to greatly delays
The generation of pest resistance to insecticide, is the important means of integrated control insect.
Nikemycin is the streptomyces ansochromogenes that Institute of Microorganism, Academia Sinica is separated to from the soil of northeast
7100 metabolins produced, belong to the biological source bactericide of broad spectrum activity, have preventive and therapeutic action concurrently.Nikemycin is to fungal cell
Chitin synthesis is inhibited in wall and insect shell, and with good selective toxicity, the toxicity to mammal is non-
It is often low.The medicine has preferable prevention effect to a variety of fungal plant diseases, insect and acarid, and category is efficient, low toxicity, low-residual
Agricultural chemicals, to plant without poisoning, to natural enemies security.Nikemycin, which is used alone, easily makes germ develop immunity to drugs, and passes through different product
Plant and compounded, can effectively anti-pathogen resistance to the action of a drug generation.At present, the complex preparation product on Nikemycin is less, no
The preventing and treating of the upper disease of production can be met.
Pyrimethanil is a kind of new, efficient anilino-pyrimidine agriculture chemicals fungicide specific drug, and its mechanism of action is to pass through
Suppress the generation of infection process enzyme, prevent germ from infecting and kill germ, to various crop gray molds, leaf mold, brown spot,
Epidemic disease, scab, sclerotiniose, spot defoliation have a good therapeutic effect.Pyrimethanil has Uptake and translocation and fumigation action, dispenser
The position that is unable to reach of the spraying such as flower, young fruit is rapidly reached afterwards, germ is killed, and drug effect is soon and stably.
The present invention is studied using existing pesticide species resource, finds Nikemycin and Pyrimethanil compositional in sterilization
Aspect has the effect of synergy.
The content of the invention
The goal of the invention of the present invention is：Answered for above-mentioned problem there is provided one kind by pyrimethanil and Nikemycin
The bactericidal composition and its preparation matched somebody with somebody, the bactericidal composition have obvious synergistic effect relative to single dose, reduce agricultural chemicals
Dosage, saves drug cost, while the not enough and insect for making up single dose improves insecticidal activity to its tolerance.
To realize above-mentioned purpose, the technical scheme is that：
The bactericidal composition of a kind of pyrimethanil-contain bactericide and Nikemycin, it contains active component pyrimethanil and Nikemycin, phonetic
The mass ratio of mould amine and Nikemycin is：1:40~10:1.
It is further preferred that the mass ratio of the pyrimethanil and Nikemycin is：1：20~5：1.
Further, above-mentioned composition can be used for making bactericide, so as to prevent and treat agricultural chemicals pest and disease damage.The bactericide
The bactericidal composition of the above-mentioned pyrimethanil-contain bactericide of active component and Nikemycin, active component accounts for the 2%~60% of bactericide gross weight,
Remaining be agricultural chemicals in allow use and acceptable composition.
In order to ensure that bactericide has more preferable insecticidal effect, preferably, the bactericidal composition accounts for the bactericide
The 20%~30% of gross weight.
Above-mentioned auxiliary material is a kind of mixture with auxiliary agent in solid carrier or liquid-carrier.It is generally used for composition pesticide
Any carrier and auxiliary agent can use.
Solid carrier includes calcium magnesium phosphate, potassium chloride, chitin, urea, ammonium sulfate, Diammonium phosphate (DAP), sodium metasilicate, peroxophosphoric acid
In calcium, humic acid, ammonium chloride, zinc sulfate, borax, montmorillonite, white carbon, precipitated calcium carbonate, diatomite, kaolin, bentonite
One or more.
Liquid-carrier include water, 1-METHYLPYRROLIDONE, trimethylbenzene, two wires oil, methyl naphthalene, methyl oleate, C10 aromatic hydrocarbons,
One or more in dimethylformamide, vegetable oil, cyclohexanone.
Above-mentioned auxiliary agent include surfactant, wetting dispersing agent, can also add if necessary antifreezing agent, thickener, defoamer,
One or more in other conventional functionality auxiliary agents such as disintegrant, film forming agent.
The formulation of described bactericide can be granule or ultra low volume liquids.
The bactericidal composition of the present invention can be prepared by the conventional method of prior art, compared to prior art,
With following beneficial effect：
1st, the bactericidal composition has obvious synergistic effect, compared with single dose, and preventive effect is improved, and dosage is reduced, reduction
Cost and the pollution to environment.
2nd, the active ingredient mixture of two kinds of different mechanism of action, synergy, achieves excellent technique effect, energy mutually
Enough delay the resistance to the action of a drug of germ, so as to reduce the consumption of agricultural chemicals, also alleviate the influence for environment, meet future society green
The trend that colour circle is protected.
3rd, composition of the invention is to preventing and treating wheat powdery mildew, rice blast, Glomerella cingulata, leaf muld of tomato, grass
Certain kind of berries powdery mildew, gray mold of cucumber etc., the effect to preventing and treating graw mold of tomato are especially good.
